Housed in a wooden, painted prototype case, the Notion Ink Adam tablet is rough. But with Pixel Qi dual-mode screen tech on one arm and Nvidia's Tegra 2 on the other, it's one of the most exciting devices at CES.

Notion Ink is apparently readying an Android tablet with a Pixel Qi display—the very same that was…

We've seen a fair share of Android 2.0 tablets at CES, some of which share not only Android 2.0 with the Adam, but the Nvidia Tegra 2 processor, too. But what they don't have is a Pixel QI transflective screen, a 10.1-inch panel that can switch between backlit LCD mode and low-power electrophoretic reflective mode, which looks more less like E Ink, and which actually gets easier to see in direct sunlight.

We got our first good look at this screen tech this morning, and we covered its weaknesses: the LCD colors aren't as vivid as a plain LCD's and suffers at some viewing angles, and the reflective mode suffers from the glossy screen's glare, but in both modes, it's good enough.

We'll get a fuller picture of the device come Mobile World Congress in February, as well as pricing info—though we're assured we'll be "very happy" about it.
